Question

Do link reaction occur during anaerobic respiration? i.e without oxygen​

Answer 1

Answer:

The production of energy requires oxygen. The electron transport chain, where the majority of ATP is formed, requires a large input of oxygen. However, many organisms have developed strategies to carry out metabolism without oxygen, or can switch from aerobic to anaerobic cell respiration when oxygen is scarce.

During cellular respiration, some living systems use an organic molecule as the final electron acceptor. Processes that use an organic molecule to regenerate NAD+ from NADH are collectively referred to as fermentation. In contrast, some living systems use an inorganic molecule as a final electron acceptor. Both methods are called anaerobic cellular respiration, where organisms convert energy for their use in the absence of oxygen.

Certain prokaryotes, including some species of bacteria and archaea, use anaerobic respiration. For example, the group of archaea called methanogens reduces carbon dioxide to methane to oxidize NADH. These microorganisms are found in soil and in the digestive tracts of ruminants, such as cows and sheep. Similarly, sulfate-reducing bacteria and archaea, most of which are anaerobic, reduce sulfate to hydrogen sulfide to regenerate NAD+ from NADH.

Anaerobic bacteria: The green color seen in these coastal waters is from an eruption of hydrogen sulfide-producing bacteria. These anaerobic, sulfate-reducing bacteria release hydrogen sulfide gas as they decompose algae in the water.

Eukaryotes can also undergo anaerobic respiration. Some examples include alcohol fermentation in yeast and lactic acid fermentation in mammals

Answer 2

Answer:

Yes, link reaction occur during anaerobic respiration. Anaerobic respiration is the process of breaking down glucose to obtain ATP in the absence of oxygen. Instead of molecular oxygen, electron acceptors are employed to generate energy in this process.

Explanation:

It's a type of breathing that doesn't use oxygen. For electron transport, elements other than oxygen are used. Nitrates, iron, manganese, sulphates, sulphur, fumaric acid, and carbon dioxide are all common oxygen substitutes. It dehydrates and decarboxylates three-carbon pyruvate to create two-carbon acetyl CoA, which can then be used in the Krebs Cycle.

Anaerobic respiration (both glycolysis and fermentation) occurs in the cytoplasm's fluid component, whereas aerobic respiration generates most of its energy in the mitochondria.
